Comment (by arma):

 Replying to [comment:42 teor]:
 > The important thing is that relays won't go backwards (like they
 sometimes do with Torflow).

 In terms of relay self-observation, we need to make sure they see load
 (from real users or from bwauths) each day (more specifically, maybe it's
 in the 24 hours before writing their descriptor) or they'll forget about
 it.

 That is, if we're trying to have a feedback cycle where we induce load,
 the self-assessed number goes higher, and then we induce more load because
 we see a higher number, then it's risky to let a day go by without hitting
 the relay with at least that level of load. (I say 'risky', not 'bad',
 because it could still turn out ok, either because some other scanner
 induces that load, or because actual users show up and induce it.)

 > Let's do this kind of optimisation in sbws 1.1.

 Sounds like a great plan.
